CONVEYER Appunti mea remargfia, 192s. seran n. :,soe.

My invention relates to conveyers comprising endless conveyer means, and1t has for its general ob'ect provide a con'- strution of thisI caracter comprising an- 1mproved andvnovel construction-of means forsupporting yinter-mediate portions of the conve er. j

It 1s also an object ofi the invention to provide a conveyer having animproved and novel construction of means at intervals for supporting theloads adapted to be transported by the conveyer from one point toanother. p I

Another object of the invention is to provide a conveyer ofnovelnconstruction, 1n-

cluding means whereby the durability of the conveyer is increased.

Another object of the invention is to rovide a construction of conveyerin w ich -1n a manner to produce a construction of great elliciency.

Other objects and advantages of the invention will be pointed out in thedetail description thereof 'which follows, or will be apparent from suchdescription.

In order that the invention may read` ily understood and its practicaladvantages fully appreciated, reference may be had to drawings, 1n whichI have illustrated certain forms of. convenient embodiments thereof.However, it will be understood that changes in the details ofconstruction may be made within the scope of the claims withoutdeparting from the inl, o Ol;

Fi 2 1s a view taken on the line 2--2/ vention.

-In the drawings,-

Fig. 3 is a perspective view showing a detail of the structure;

Fig. 4-is a view in side elevation of a portion of the structure, and inwhich an object which is being transported thereby is indicated in dashand dot lines;

Fig. 5 is atransverse sectional view Vshowing a modified construction ofconveyer portion of the structure showing a detail of construction invFig.l 8 is a perspective view of an element ofthe construction; and

Fig; 9, is a view in side elevation of a portion of the conveyorstructure shown in Fi 5.

Re erring to the drawings, it will be noted that the frame structure ofthe apparatus comprises cross-wise extending members 1 arranged atintervals. These members in the construction as illustrated consist ofangle plates, but it will be understood that other shapes may beemployed. Posts or `standards 2 of angle members, or members of othershapes, are secured at their lower ends by means of rivets 3 to theopposite ends of the cross-wise extending members 1 and extend upwardlytherefrom. These are connectedintermediate their ends by cross-wiseextending bars 4 of channel shape, but bars of any other shape in crosssection may be emplo' ed. The upright posts or standards 2, w ich arelocated at intervals on opposite sides of the structure, are alsoconnected by longitudinally extendplates 5.

llteferrin now to Figs. 1 to 4, inclusive, it will be ogserved thatangle members 6 and 7 are secured by means of rivets 8 to the upper endsof the posts or standards 2, and that the said angle members extend lontudinally of the structure at substantia ly right angles to the crossmembers 1 and 4; One flange of each of the angle members 6 and 7occupies a vertical position, the flange 7 overlying the flange 6. Theother flange of each of the said members extends inwardly as indicated'at' 9 and 10. These flanges are spaced from each other, as indicated inFig. 1 of the drawings. The flange 10 of each angle is provided withnotches or openings 12 at intervals for a purpose to .be hereinafterreferred to. In addition to the angle members 6 and 7, angle members 15are secured to the tops -of the posts or standards 2 with the horizontalflanges 16 thereof in the same plane as the horizontal flanges 9 of theangle plate 7. The flanges 16 and 9 operate to form a platform structureat the opposite sides of the conveyer structure. The vertical flanges 17of the angle members 15 constitute and form outer sides of the platformformed by the horizontally extending flanges 9 and 16.

Conveyer chains 20'1ocated at the opposite sides of the structure aredriven or operated by any suitable means (not shown).

tra

The upper portions or sections of these chains occupy ositions betweenthe inward ly ext/ending anges 9 and l0. Shafts 22 are supported atintervals upon these chains.

' secured thereto nearthe opposite ends there of in adjacent relation tothe inner members of the bearings 23. Nuts 29 upon the opposits ends ofthe shafts engage the outer members of the bearings so that the members23 of said bearings are clamped between nuts 29 and collars 27. It willbe seen that in this way each of the shafts 22 is connected with theconveyer chains at the opposite sides of the structure, and that therebythe said chains are bound rtogether to form a unitary conveyerstructure.

Cylindrical load supporting members 30 are mounted upon the shafts 22.ln the construction as shown these load supporting members 30 aretubular or hollowT for the sake of lightness, but it will be understoodthat, if preferred, these cylindrical members may be solid.. The upperportions or sec tions of the chains 20 are supported upon-tho supportingrollers 3l mounted near the opposite ends of shafts 32 The rollers 3lare rotatable upon the shafts 82, or, if preferred, the shaftsthemselves may be rotatably mounted in their bearings. llhe rollers 3lare held in place upon the shafts 32 by means of collars 33 mounted uponthe opposite end portions of the shafts in spaced re lation toeachother.

The opposite ends of certain of the shafts 32 are supported in theupright posts or standards 2, while others thereof are supported inbrackets 35 which are secured to and depend from the upright flanges ofthe angle members 6 and 7. The rollers 3l project upwardly through theopenings l2 in the horizontal flanges of the angle members 6 so that theupper horizontal portions or sections of the conveyer chains are adaptedto be supported thereby. Said portions are also supported upon the uppersides of the horizontal portions l0 of the angle meme bers Forsupporting the lower horizontal portions of the conveyer chains l haveprovided traclas 40 supported upon the upper edges ci' the cross barsl.V The cylindrical load su .ng members 30 rest upon the upper edges ofthese tracks and inenten chains 20 are supported upon the rollers 31,

the-said shafts and load supporting means do not rotate, but when in theoppos1te position, with the load supporting means 30 resting upon thetracks 40, rotation of said load supporting means and the shafts 22 iseffected. Suchrotation facilitates the linear traveling movement of theconveyer chains the shafts 22 are rotat- I and reduces the friction,which is necessary to be overcome by the power means by which the chainsare driven.

'lhe load 4l, shown in dash and dot lines in Fig. llof the drawings, issupported upon a plurality of adjacent load supporting i members 30 andmay be transported thereby from one position to another.

Referring now to Figs. 5 to 9,' inclusive, of the drawings, it will benoted that'the upper ends of the posts or standards 2 are connectedtogether by the vertical flanges 44 of the longitudinally extendingangle members 45. The horizontal flanges 46 extend inwardly and overliethe upper portions or sections of the chains 20. Channel bars 47 extendbetween the chains 20a. The flanges of said channel bars extendoutwardly, as indicated :fn Figs. 5 and 6 of the drawings, and the oposite ends thereof, which are reduced as indicated at 48, extend throughalternate links of the donveyer chains. The inner sides of the linksthrough which the opposite ends of the channel members 47 extend Contactwith shoulders 50. Retaining filler blocks 5l are secured by rivets 52to the.

opposite ends ofthe channel members between the flanges thereof. rlheinner ends of these filler blocks are provided with outwardly extendingprojections53, which contact with the outer sides of the links of thechain through which the opposite endsof the channel members extend. Eachof the channel members 47 is provided with upwardly extending angularvsupporting members 55. 'lhese supporting members are secured to theflanges of the angle members and are arranged in couples near theopposite ends of the channel members. At their upper ends these angularsupporting members are provided respectively with outwardly extendingportions 56, to which the load supporting platforms 57 are `'secured byrivets 58. rlhese load supporting platforms extend transversely of thestructure with their opposite ends located in adjacent relau tion to theinner edges of the horizontal anges 46 of the angle members 45. The

las

wheels 31 mounted upon shafts 32, certain of which are supported attheir opposite ends in oppositely disposed posts or standards 2, whileothers thereof are supported in depending bracket plates 35a. Thesedepending bracket plates 358 are secured at 1ntervals to the verticalflanges 44 of the angle members 45.

'Ihe lower portions or sections ofthe conveyer chains 20a are supportedupon rollers or wheels 61 rotatably mounted near the opposite ends ofshafts 62, supported at their opposite ends in the longitudinallyextending plates 5. The wheels 61 are retained in place by means of thecollars 63, located upon the opposite sides-thereof, and secured to theshafts 62l Instead of the rollersv or wheels 61 being rotatably mountedon the shafts 62, they may be rigidly secured thereto, in which case theshafts 62 should be rotatably mounted upon the supporting plates 5. Ifpreferred, not only may the shafts 62 be rotatably mounted, but therollers or wheels 61 may also be rotatably mounted upon the said shafts.1

Secured at intervals to the vertical flanges 44 of the angle members 45are angle clips or brackets 64, upon which the horizontal flanges 65 ofangle members 66 are supported. The vertical flanges 67 of these anglemembers constitute guards for the platform formed by the horizontalflanges 46 and 65.

The conveyer chains 20a may be driven by any suitable power means (notshown).

The conveyer structures as illustrated and described are designedprimarily for transporting molds employed in connection with provided asimple and durable construction by the employment of conveyer apparatus,

be transported most of which objects may `eiiciently and convenientlyfrom one point to another.

Having thus described my invention, what I 4claim and desire to secureby Letters Patent is:

1. In conveyer apparatus, of flexible endless conveyer means located inparallel spaced relation to each other, rotatable bars extendingtransversely of and conneeted at their opposite ends to the saidconveyer means,which bars areadapted to support loads to be transportedby the said 'conveyer means, combined stationary and rotatablesupporting means for supporting the upper portions of the said flexibleconveyers, and means for supporting the said load supportingl means andthe said conveyer means w en the latter occupy their lower position. v 4
